This is going to entail some more work. I installed CPU Director (CPUD)

here is where it gets interesting. With the L3 turned off in CPUD,
xBench still shows a L3 cache.
CPU tests 20% HIGHER with no L3 cache
Memory tests 25% lower with no level 3
Quartz Graphics 30% lower no L3
User interface 40% lower no L3
Disk test almost no difference

Well, I don't know what to make of that. Is Any thoughts out there?
xBench shows the L3 cache as active even when CPUD turns it off, or is
just
showing it present? Well you do see a difference in the tests on or
off, but
you could cross check in Profiler, I guess, to make sure.
xBench doesn't say on or off. System Profiler does NOT show a L3 when
CPUD turns it off.
